HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 326,418, datedSeptember 15, 1885.

Application tiled March 5, 1884.

To all whom it may concern:

Be it known that I, WILLIAM A. FoRoE, a citizen of the United States,residing at Brooklyn, in the county of Queens and State of New York,have invented new and useful Improvements in Hand-Stamps, of which thefollowing is a specification.

This invention relates to improvements in handstamps having a series ofrotating numbering-wheels therein, and means for causing said Wheels tobe turned when the stamp is operated, the object being to provideimproved means for intermittently rotating the number-wheels, forcausing the stamp to repeat a number as many times as may be desired,and for so setting the stamp-operating devices that any number shall beprinted in duplicate.

In the drawings forming part of this specification, Figure 1 is anenlarged view of a handstamp embodying my improvements. Fig. 2 is a sideelevation showing the print ing devices in an intermediate positionbetween their upper and lower one. Fig. 3 is a rear elevation. Fig. 4 isa side elevation, partly in section. Figs. 5 and 6 illustrate de tailparts.

In the drawings, 0 is the frame of the stamp, having thereon the usualopen baseplate. E is the number-wheel frame, having thereon the tubularhandle h, within which is the coil-spring a. The handle as usual passesthrough a cylindrical collar on frame G, through which a pin passesunder said spring a. The sides of frame 0 are slotted, and screwspassing therethrough into the wheelframe E serve, together with thehandle 71 to guide said frame properly when moving up and down.

Two arms, J, extend rearwardly from frame 0, on which is hung theinking-pad ease K, between the inner sides of which is the lower part offrame E, the latter having rearward extensions through which,transversely, is a pivot-pin, 12, whose ends engage in slots in thesides of the case K, as shown in Figs. 1 and 2.

A pawl-yoke, A, is pivoted between said extensions of frame E on the pinit, and the upper end of said yoke is pivotally connected with the frame0 by the connecting-bar B.

The number-wheels c are hung on the shaft (No model.)

it in frame E, and on the side of each is the usual ratchetwheel, 0'thereto fixed. A noted idler-wheel, (Z, is also hung on the shaft t,next to the outside of the first numberingwheel. lVheel d is fully shownin Fig. 5. The first numbering-wheel, above men tioned, is the one atthe left, looking at the front of the stamp, or the side on which is thespringfinger plate m, Fig. 1.

A cries of pawls, e, is rigidly secured by one end to ablock, 0, thelatter being pivoted in the yoke A, and the hooked ends of the pawlsextend over the edges of the ratchetwheels 0 on the wheels 0, and areadapted to engage with said ratchet-wheels and turnwheels 0. A spring,1), is secured by one end to the pin a and passes up back of a bar, a",whereby its free end is made to bear against the upper edge of the block0, thereby forcing downward the ends of the pawls 0 against wheels 0 Thehooked lever b is secured to a block, as shown in Fig. 5, through whichthe shaft 0*, on which the block 0 is hung, passes, and lever b swingsfreely on shaft 0, and when not interfered with its hooked end rests onthe idler-wheel d.

A turn-button, i, is placed in block 0, near the side of the block towhich the lever Z) is secured, the base of which is cut off on one side,as seen in Fig. 3. When said button is in the position there shown,block 0 may oscillate without swinging the block on which is the lever12, but when the button '5 is turned to bring its base on the block towhich lever b is secured, the end of the latter will, by spring 1;acting on block 0, be forced down onto the edge of wheel (I.

A cam-lever, D, is hung on the wheel-shaft t, in frame E, at the side ofthe ratchet-wheel c, on the adjoining wheel 0. The pawl e, which turnsthe said wheel 0, may swing down freely, together with the other pawlswhich ale on block 0 when leverD is in the position shown in Fig. 1thatis to say, with its fingerpiece 3 downward-carrying its rim from underthe thickening boss 5 on the side of the pawl, but when the finger-piecey is carried up, the rim of lever D strikes the boss 2 and swings theends of all the pawls a up and holds them away from the ratchet-wheels0", so that when the pawls reciprocate by the swinging of yoke A thenumbering-wheels c are not turned, and the stamp repeats a number aslong as the pawls are so held up.

\Vhen the handle it is driven down, the frame E and the parts theretoconnected have the same movement, and, since the upper end of yoke A isconnected by ba'rB to frame 0, said downward movement causes the upperend of the yoke and the pawls e to move toward the upper part of frameE, carrying the pawls over the ratchet-wheels c. with which they engagein turn, as above described, and the action of spring a, in drawing upframe E, causes yoke A to swing outward and the wheels 0 to be turned.

The above described means for working the pawls which rotate thenumber-wheels in a stamp of this class contribute greatly to the steadyworking of the machine and obviate the usual jarring motion which causesimperfect printing.

In operating the stamp to repeat a number, it is accomplished byproviding means, above described, for permitting the pawls c toreciprocate twice, but in so doing to act on the number wheels but once.The features of construction which contribute to this result are theabove-named wheel (I, lever Z), and button t, acting in conjunction withthe block 0. Thus when the lever b is left free the pawls c act to turnwheels 0 each time frame E goes up, but when said lever is made to swingwith block 0 its end will first drop into one of the deep notches onwheel (Z, but when next lifted and let fall it will ride on the edge ofthe wheel and thus hold the pawls up, but at its next movement it willagain drop into a deep notch as before. Thus the wheels are retated onlyafter two impressions of the stamp by simply turning button 23 so thatits base is over the block on which lever b is secured. The engagementof the ends of the pin a in the slots in the sides of the ink-pad case Kcauses the latter to swing from under the wheels 0 when frame E isforced down, and

the upward movement of the latter swingsframe E, are made by thespring-fingers w to press against the edges of the ratchet-wheels a andhold wheels 0 from rotating out of time.

What I claim as my invention is- 1. In combination, the yoke A, thepawls c, pivoted in said yoke, one of said pawls provided with boss .2,the series of numberingwheels, and the cam-lever D,-said wheels andcam-lever mounted on a single shaft, substantially as set forth.

2. In combination, the frame E, the frame 0, the yoke A, movably pivotedat a, the pawls a, and the numbering'wheels, the bar B, and theinking-pad case slotted to receive pivots a, substantially as described.

3. In combination, yoke A, block 0, pivoted in said yoke, a series ofnumbering-wheels provided with ratchets, pawls e, engaging said rachets,spring 12, lever b, idler-wheel (I, and the button 2', substantially asset forth.

4. In combination in ahand-stamp, a series of numberwheels provided withratchetwheels, as described, a notched idler-wheel on same shaft withnumber-wheels, a series of pawls to engage said ratchet-wheels and apawl to engage said idler, a button by which said pawls may be connectedor disconnected, as described, and mechanism by which the pawls arereciprocatcd, substantially as described.
